Hi - got a problem with IIS7 / Exchange 2007 / server 2008 SBS where we have to iisreset every 40 minutes or so in order to get the /autodiscover/autodiscover.xml file to work:

usually get the correct 'error 600 invalid request' but then as suggested every 45 minutes or so get a 'access is denied' - iis reset, back to error 600.

not sure where the logs are or why this keeps happening but it's not bloody good.

Is your server completely upto date?
Run Windows update and clck to check online for updates.

Also try running the fix my network wizard: http://blogs.technet.com/sbs/archive/2008/11/26/introduction-to-the-fix-my-network-wizard-fncw.aspx
This was caused by loopback addressing or alias addressing where the autodiscover.local.local was missing from the registry entries (I think)

reinstalling autodiscover then RPC along with regedit sorted it out! (thank the lord)
